To all 'whom it may concern Be it known that I, ROBERT FLnnrwooD NICHOLS, a citizen of the United States, and a resident of Oakland, in the county of Alameda and State of California, have' invented new and useful Improvements in Casement- Windows, of which the following is a full and exact description.

I am cognizant of the fact that easement windows are in use that swing inward; such easements are very satisfactory iny fair weather ,for cleaning the outer fronts of the easements, for full ventilation, etc. In stormy weather they are a source of annoy ance on account of rain or snow being driven through the outer fronts of the easements. Heretofore architects, builders and others have been unable to so design and construct easement windows as to make them storm erence indicate proof from the outside, and the easements, singly or collectively, readily swing inward so as to permit the use of outside screens for ventilation and other purposes.

The object of the invention is to overcome this difliculty and so construct a easement window that when the easements are in their normal position in the easement frame they will be proof against storms from the outside and readily, singly or collectively, swing inward to clean their outer panes, for ventilation and other purposes, also permit the use of outside screens to prevent ,the ingress of flies, mosquitos, ete.

The invention consists in the novel construction and combination of the several parts,` as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speci- `fication in which similar characters of refcorresponding parts in all the figures.

Figure l is a front elevation of a easement window frame, having the improvements applied thereto, and illustrating the case-l ments, the closing bar, and turn buttons to secure 'the closing bar to the easements. Fig.

49. is a horizontal cross section through Il,

Fig. l, amd,i illustrates the left hand easement jamb, rabbets formed in the jambe and grooves formed-in the rabbets; also illustrates the hanging stiles of the easements,

'grooves formed-fn the hanging Stiles con- `necting with like grooves formed inthe rabr betsofthe easement j a-rnlis; grooves' formed ir. the inner edges of the' hanging Stiles', and

hinges to connect the easements with the easement jambe. Figj is a detailed horizontal cross section 4through Gr, Fig. l, and illustrates the inner and outer fronts of the meeting stiles of the easements B, B, the form of the rabbets and lips in their inner and outer edges, the grooves formed in the outer lip` and rabbet of the meeting stiles. Also it illustrates the rabbet and lip in the inner fronts of the meeting Stiles, as being of greater'depth outward, than the rabbet and lip in the outer fronts of the meeting stiles are inward. Fig. 4 is a detailed perpendicular cross section through C, Fig. l. This section shows the window sill, E, the closing bar l), the lower section of the right hand stile F of the left hand easement B, and an inner section of the lower rail of a easement; also illustrates the manner of forming the window sill, E, the closing bar, D, the perpendicular groove in the lip of the right hand meeting stile F of the left hand easement B, the rabbets formed in the inner lower edges of thc lower rails of the easements. It further illustrates the outer and lower lip of the .closing Aloar D, as overlapping the upper and inner lip of the window sill E and the outer lip in the lower edges of the easement rails as overlappingthe upper and inner lip of the closing bar D.

A, represents a easement window frame, l?, B, the easements, F, F, the easement stiles, E, the window sill and l?, the closing bar, the easement frame A. being provided with rabbeted jambs L, Fig. 2, a window sill E and the usual finish for easement windows. The rabbets in the easement jambs I, form recesses to receive the easements B, B'. Hinges S carry the easements B, B. Perpendicular grooves, 6, are formed 4in the inner front edges of the rabbets of the easement jambs Il. The window sill E on its inner upper edge 2 is provided with a lip 7 Fig. l; in the outer front of the lip 7, a longitudinal semicircular groove 10 is formed. In'the lower outer front of the lip 7 a. similar longitudinalsemicircula-r groove 13 is formed to connect withand form a part of the-outward and downward. lslope of the window sill E@ The closing har D on its inner front and lower edge is provided with a rabbet I to form a lip 14, in the lower and outer front of the closing bar D, to connect with the lip 7 and form a closure with the window sill FJ. In the inne front of the lip 14, a longitudinal semicireular groeve El is formed to conico neet with a like groove 10, formed `in` the outer front of the lip 7 of the window sill E to prevent water passing up by capillary attraction, through the lip 7 of the window sill 'E and the lip 14 of the closing bar D. In

. 4the lower and inner edge .of the lip 14 of the -elosing bar D a longitudinal vsernicircular is cut away to form 'an inner lip 15 and the upper edge 16 of the lip 15 is sloped down ward and outward. In'the lower and outer "front of the lip 15, a longitudinal semieireular groove 18 is formed. lInterseeting'with ,the groove 18 at an acute angle '21 the outer.

front of the closing bar D is sloped down- .ward to a point 22. The closingbar D is connected with the window sill E by means f hinges 9 secured to theupper-and inner edge 2 of the window sill E and the ,lower and inner edge 1 of .the closing bar'D. The

objeetjof sloping the closing bar D atan acute angle 21, is that when the closing bar I.

" meeting stiles,would pass down the perpem D is turned inward by means of the hinges 9, it will pass clear of the lower edges of the lips 19 of thel easements B, B.- Tlie casements may theny be singly or collectively swung inward and replaced in the easement frame A; the closing ,bar D can then be re- 'f turned to its normal position in 'thel easement frame A and form a closure withv the window sill E and the easement`s"`B,B, illus- I,

to form channels or outlets to pass off water driven between the hanging stiles F, F, and

the easement jambs L. As an additional. protection from storms, grooves 3, 3 are formed in the inner edges of the hanging stiles F, F.

Rabbets 17, 17 are made in the lower inner edges of the easements BB, to form lips 19 in the 'lower edges of the outer fronts of the easements B, B. The rabbets 17 are sloped downward and outward to conform to the slope 16 in the upper edge of the lip 15 of the closing bar D. Wh'en the closing bar D is in its normal position in the easement frame A, it is held in that position by meansY of turn buttons 28, 28, secured to the inner front of the lower rails of the easements B, B.

In vthe inner fronts of the easements-B, B, the right hand meeting stileF of the left Stiles are of hand easement B is provided with a rrabbet 23 and the left hand meeting ,stile F of the right handeasement B, is provided with a. Y lip 24. In the outer fronts of the easements 'B, B, theleft hand meetingstile-"F, of the right hand easement B,`is provided with a rabbet 25, and .the right hand meeting 'stile F of the left handeasement B, isprovid'edwith a lip 26.` In the edges of the rabbet'25 I and the l-ip 26 perpendicular Asemieireula'rfiggy of the meeting Stiles are inward. The object f of this is, that the lip 15 of the closing bai: A8,13 i. D, and-the lip 19 in the lowerA edges of thef easements B, B, form :i longitudinal closure;v within the lines of the perpendicular rabbet` l 25, and the 26, in the edges ofthe meeting st iles inthe outerv fronts of the easements B, B, so tliat any water driven between the easement Stiles and the-easement jambs `or between therabbet-25 and the lip 26 ofthe dicular grooves in the easement stiles and easement jambs to tlie slope 21 the outer v' front of the closing bar D, off the elosingf bar D to the window sill E and out of the easement `frame A. y A A It can readily be seen thatthe perpendieu- "10o lar grooves 6, 6, formed in the inner. front edges of the easement jambs L, the grooves 3, 3, in the inner edgesof the hanging stiles,

the grooves 4, 4, in the outer fronts of the hanging Stiles, the grooves 27, 27, in the les,

outer rabbet 25 and the outer lip 26 ofthe meeting stiles of the easements B, 5B, the l intersection of the lip 15 of the elosi'lng'bar D with the lips 19 of the lower rails of the 1 easements B, B, the intersection of thelip 7 11G'` 1, of the window' sill E withgthe lower lip -14I5 v of the closing bar D, the longitudinal..

,grooves 10 -and 13`in the lip"7 of the window sill E and the like grooves 11 and 12 i'n the lower lip 14 of the closing bar D, make the 1 15 easement window impervious to .rainr orv snow and storm'proof.

When it is desired to V open the easements B,1 B, the turn 'buttons 28, 28 are turned from the perpendicular'` to the horizontal position 120 shown in Fig. 1. The easements B, B, can then be swung inward, the lower railsof the easements B, B, turning the closing bar D,

` from the perpendicular to the horizontal position illustrated by the dotted lines in Fig.

- 4. It is plainly to be seen that when the closing bar D, yis in the horizontal position the easements B, B-,wi'll pass freely over the outer front of the closing bar D inward, and as freely pass over it when being replaced mesme A in thev easement frame When the 'casei ments B, B, Aare in their normal positions` y tion. I

' devices used forxmany fore do not make any elaimtoithem as rabnormal perpendicular position in the case- -ment frame A, the upper lip 15 of the closing bar D formmg a closure with the lips 't 19, 19 in the lower rails of the easements B,

i B, h 10 vlower lipl 14 of the closing bar D forming a closure with the lip 7 of the window sill E. The-turn buttons 28 28 are returned from the horizontal, totlxe perpendicular position securingthe.closing bar D firmly to the easements B, '.B,1 so that the easementslB, B, and the-closingbarD can not be removed until the turn buttons 28, 28 are 'again returned to the horizontal posi, desire it to be understood'that other devices may be employed in place of the turn buttons, without departingafrom `the spirit of the invention.
